| Abstract: |
| First,influencing factor and changing range of asphalt foaming were evaluated by laboratory test.Second,foamed asphalt mixture was prepared with different foaming rate and their physical and mechanical properties were tested for clarifying the relationship between foaming rate and foamed asphalt mixture. Third,mixing process of foamed asphalt mixture was simulated to study how mixing and moving aggregates affected asphalt foaming.Finally,propositional value of foamed asphalt evaluation index is indicated as its application guidance. |
| Key words: foamed asphalt,foaming effect,expansion ratio,half life,indirect tensile strength |
